Show LONG RESTS OFTEN' NEEDED When One Is Too Exhausted for Any Kind of Work He Must Drop It Absolutely for a Time. What is the relation between exercise exer-cise and rest? Work is that at whict we must contiime, whether interesting or not, whether we are tired or not. It used to be thought that the prime requisite of rest was the use of faculties other thsn those involved in the labor of the day. But there is such a thing as fatigue which goes deeper than daily work. We can work so hard as to become exhausted too exhausted for any kind of work. Perhaps this is will fatigue. It is coming to be regarded regard-ed as fundamentally true that rest from such fatigue demands continuity; continu-ity; that, for example, four periods of 15 minutes each of rest is not the equivalent of the hours rest; that a man who goes on a vacation and takes half an hour of his business busi-ness work every day is doing the same thing as the man who had a horse with a sore back. He kept the saddle on only a few minutes each day, but the sore did not have a chance to heal. Rest periods must he sufficiently consecutive to overcome over-come consecutive fatigue.
